Product details

What this 2-pole C-curve 50 A MCB delivers

Overvoltage category 3 and energy limiting class 3 mean it coordinates well downstream of a higher-rated main breaker.

Snaps onto standard 35 mm DIN rail, occupies 2 width units (about 36 mm), and has a 55 mm installation depth — no surprises for a panel already laid out for SENTRON 5SQ-series breakers. IP20 finger-safe terminals are standard for enclosed distribution boards. The 1P+N design means you get neutral switching in a 2-module width, which is tighter than a 4-pole unit for single-phase final subcircuits.

Frequently asked questions

Where can I buy 5SQ2570-0KA50?

Sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.

What does the 1P+N pole configuration mean for wiring?

1P+N means the breaker switches both the phase conductor and the neutral conductor simultaneously, with the neutral pole rated to carry the full 50 A load current. This is typical for single-phase final circuits where disconnecting the neutral is required by local code.

Will 5SQ2570-0KA50 drop into a panel that was specified around 5SQ2670-2YA16 without rewiring?

No — the 5SQ2670-2YA16 is a 4-pole (4P) breaker with 16 A rating at 400 V, while the 5SQ2570-0KA50 is a 2-pole (1P+N) 50 A unit at 240 V. Different pole count, current, and voltage; the panel busbar and circuit wiring would need to be reconfigured.
