Product details

63 A, 2-pole C-curve MCB for distribution boards

Rated breaking capacity is 3 kA Icu at 400 V AC 50/60 Hz per SANS 60947-2, with the service breaking capacity (Ics) at the same 3 kA — meaning it can clear a fault and be returned to service without derating. Limitation class 3 per SANS 60947-2 keeps let-through energy low enough to protect downstream components in a coordinated panel.

Clip-on mounting to DIN rail (35 mm per EN 60715) — no tools needed for installation or removal. At 36 mm wide (4 x 9 mm pitches) and 81 mm tall, it occupies two standard modular positions in a distribution board. Depth of 66.5 mm leaves clearance for wiring in shallow enclosures. IP20 finger-safe protection on the front face; suitable for dry indoor panels only.

Lifecycle and compliance posture

Electrical durability is rated at 4000 cycles, mechanical at 10000 cycles — figures typical for a residential or light-commercial distribution MCB.

Frequently asked questions

What is the breaking capacity of EZ9F53263?

The EZ9F53263 has a rated ultimate breaking capacity (Icu) of 3 kA at 400 V AC 50/60 Hz, with the service breaking capacity (Ics) at the same 3 kA — both per SANS 60947-2. This is sufficient for most residential and light-commercial distribution boards where the prospective short-circuit current stays under 3 kA.

What compliance documentation does Schneider provide for EZ9F53263?

The breaker is certified to SANS 60947-2, the South African national standard for low-voltage switchgear. It carries IP20 protection per IEC 60529 and is rated for isolation per SANS 60947-2. Specific RoHS/REACH declarations are available from Schneider's documentation portal for the Easy9 range.

Where can I buy EZ9F53263?

The EZ9F53263 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the current supply position.
