Product Details:
- SQUARE D BDA34125Y PowerPact B Series circuit breaker designed to offer protection by cutting off the electrical supply in the event of short-circuit and overload occurrences
- Type B design allows tripping at faulty currents rated 3 to 5 times the preset amperage values; ideal for lighting, solar, telecom and railway signalling applications
- Features a fixed instantaneous, thermal-magnetic trip unit adjusted to a pre-determined overcurrent value (.05 - 0.5 sec) for accentuating the control toggle when exposed to current surges
- NEMA-rated, UL-listed and CSA-certified
