Product details

The Schneider Electric C12E44V160B is a 4-pole ComPacT NSXm moulded-case circuit breaker rated 160 A at 40 °C, with a 16 kA interrupting capacity at 415 V AC (performance level E). It carries an electronic MicroLogic 4.1 trip unit that integrates earth-leakage protection — selectable sensitivity from 30 mA to 5 A, class A or AC — so you can cover both overcurrent and ground-fault in one device without an add-on module. The 108 mm width and 144 mm height fit a 12-module pitch at 9 mm per module, so it occupies a predictable footprint in a standard panel layout.

Trip unit and protection detail

Earth-leakage sensitivity is field-selectable across 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, and 5 A for class A (pulsating DC) and class AC (sinusoidal AC) faults. This range lets you tune the ground-fault threshold to the load — 30 mA for personnel protection on a lighting subfeed, 300 mA or higher for equipment protection on a motor circuit.

Front-connect terminals accept compression lugs or busbars. Connection pitch is 35 mm with spreaders, 27 mm without. Auxiliary contact presence is indicated by a green flag on the front face. IP40 enclosure protection and IK07 impact resistance are standard for the panel environment.

Frequently asked questions

What is the breaking capacity of C12E44V160B?

Performance level E gives 16 kA at 415 V AC, 50/60 Hz, per IEC 60947-2.

What earth-leakage sensitivities are available on this MCCB?

The integrated earth-leakage protection is field-selectable: 30 mA, 100 mA, 300 mA, 500 mA, 1 A, 3 A, or 5 A, for both class A (pulsating DC) and class AC (sinusoidal AC) fault types.

Where can I buy C12E44V160B and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
