Product details

The Schneider Electric EZC100B3040 is a 3-pole molded case circuit breaker from the EasyPact EZC100B series, fitted with a thermal-magnetic TM-D trip unit rated 40 A at 50 °C. That 40 A rating governs the continuous load it can carry in a distribution panel — sized for a 40 A feeder or branch circuit, not a motor-starting duty. At 440 V AC the breaking capacity drops to 5 kA Icu; at 550 V AC it is 2.5 kA Icu, so verify the available fault current at your service voltage before specifying.

Backplate-mounted, fixed (non-pluggable). The toggle actuator gives positive contact indication (ON/OFF status visible on the breaker face).

Certified to IEC 60947-2 (the main MCCB standard for industrial applications), IEC 60947-1 (general rules), JIS C8201-2-2 (Japanese industrial standard), and GB/T 14048.2 (Chinese national standard). Rated insulation voltage 690 V AC; operational voltage up to 550 V AC. Mechanical durability 13,000 cycles — a standard duty-cycle life for fixed-installation distribution breakers.

Frequently asked questions

Where can I buy the EZC100B3040 and get a price?

The EZC100B3040 is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm current pricing and availability; no stock or price figures are published here.

What is the breaking capacity of the EZC100B3040 at different voltages?

The breaking capacity varies with voltage: 10 kA Icu at 110-130 V AC, 10 kA Icu at 220-240 V AC, 7.5 kA Icu at 380 V and 400-415 V AC, 5 kA Icu at 440 V AC, and 2.5 kA Icu at 550 V AC — all per IEC 60947-2. Verify the available fault current at your service voltage against these ratings.

What compliance documentation does the EZC100B3040 carry?

Certified to IEC 60947-2, IEC 60947-1, JIS C8201-2-2, and GB/T 14048.2. Suitable for isolation per IEC 60947-2. Rated pollution degree 3 per IEC 60664-1. The manufacturer provides full IEC compliance documentation with the product.
