This is a 1-pole DZ47 / C45N-series miniature circuit breaker (MCB) with C-curve tripping characteristic, available in 3 A through 63 A current ratings, designed for DIN-rail mounting in residential and small commercial distribution boards to protect lighting and general-purpose circuits against overload and short-circuit faults. 6 kA breaking capacity, 230/400 V AC operation, IEC 60898-1 standard, CE certified.
Product Description
This is a single-pole miniature circuit breaker in the well-established DZ47 / C45N footprint, sized for 35 mm DIN rail mounting in residential consumer units, small commercial distribution boards, and machine control panels. The C-curve tripping characteristic (5–10 In instantaneous trip) makes this the right choice for general lighting circuits, socket outlets, and resistive loads where typical inrush currents are moderate.
Available current ratings cover 3 A, 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, and 63 A, allowing one product line to protect everything from individual light circuits up to a complete sub-board feed. The 6 kA breaking capacity is appropriate for typical residential and small commercial fault levels; for higher-fault-level installations (large industrial sites with high prospective short-circuit current) a 10 kA breaker is required.
Key Benefits
- 10 current ratings (3–63 A) cover lighting circuits, sockets, and sub-board feeds in one product
- C-curve tripping (5–10 In) is correct for general lighting and socket outlet protection
- 6 kA breaking capacity meets IEC 60898-1 for residential and small commercial use
- 35 mm DIN rail mounting fits any standard residential or commercial distribution board
- 20,000 mechanical operations + 6,000 electrical operations means decades of service life
Key Features
The defining feature is the IEC 60898-1 compliance combined with the DZ47 / C45N footprint that is dimensionally interchangeable with breakers from major industrial brands across most of Europe, Latin America, and Asia. This means you can use this product to populate a new distribution board, or to add circuits to an existing one, without compatibility concerns. The C-curve tripping characteristic is the right default for general residential and light commercial use; it tolerates moderate inrush from lighting and socket loads while still tripping fast on actual short-circuit faults.

What's Included
- 1 x DZ47 1-pole MCB (per selected current rating)
Compatibility & Applications
This MCB fits any 35 mm DIN rail in a distribution board sized for the DZ47 / C45N footprint. Typical applications include:
- Residential consumer unit final circuits (lighting, sockets, ring mains)
- Small commercial distribution board sub-circuits
- Machine control panel branch protection
- Solar PV system AC-side protection (within 6 kA fault level)
- Workshop and garage circuit protection
Not suitable for: installations with prospective short-circuit current above 6 kA (use a 10 kA MCB), motor starting circuits with high inrush (use a D-curve MCB), DC circuits (this is an AC-rated MCB — use a dedicated DC MCB for solar PV DC strings), or installations requiring residual-current protection (combine with a separate RCD or use an RCBO instead).

Important safety note: circuit breaker installation must be performed by a qualified electrician in accordance with local electrical codes. Incorrect MCB selection or installation can cause fire and electrocution hazards.
Frequently Asked Questions
Which current rating should I choose?
Match the rating to the cable size and load type: 6 A for individual lighting circuits, 16 A for general lighting and small power, 20 A for kitchen socket circuits, 32 A for cooker or instantaneous shower circuits, 40–63 A for sub-mains feeds. The MCB rating must be equal to or below the protected cable's current-carrying capacity. If unsure, consult a qualified electrician — incorrect MCB sizing is a fire risk.
Why does the C-curve matter?
Tripping curves describe how fast the MCB trips in response to overload. C-curve trips the magnetic element at 5–10 times rated current, which is correct for general lighting and socket circuits where moderate inrush is normal. B-curve (3–5 In) is for purely resistive loads and is more sensitive; D-curve (10–20 In) is for motor circuits with high startup inrush. Using the wrong curve causes nuisance tripping or under-protection.
Can I use this on my solar PV system?
On the AC side of a solar inverter, yes — this MCB is appropriate for the AC output circuit between the inverter and the consumer unit. On the DC side (between the solar panels and the inverter), no — you need a DC-rated MCB designed for the higher arc-extinguishing demands of DC circuits. Solar DC strings typically need a 1000 V DC-rated MCB, which is a separate product category.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this MCB compare to others in its category?
Within the 1-pole AC MCB category, the meaningful comparison points are breaking capacity, tripping curve options, current rating range, and form-factor compatibility. This product offers 6 kA breaking capacity, C-curve tripping, ten current ratings from 3–63 A, and the standard DZ47 / C45N footprint — the configuration that fits the largest installed base of residential and small commercial distribution boards and drives the lowest return rate within our circuit-protection category.
