Industrial W91-X113-10 Circuit Breaker

TE Connectivity Potter & Brumfield W91-X113-10 is a magnetic hydraulic circuit breaker designed for panel-mount protection in 277 VAC circuits. This 1‑pole device carries a 10 A rating and employs a hydraulic delay with a magnetic trip mechanism to provide short-circuit protection while suppressing nuisance trips from brief surges. Part of the W9 family (alias W91-X11310; TE internal 3-1393254-4), it features a black lever actuator and is intended for panel mounting with a bolt‑connection footprint. The unit offers a 5 kA interrupting capacity at 277 VAC and a trip time of approximately 0.15 to 1.5 seconds at 200% overload. Physical dimensions include a 0.75 in × 2.065 in cutout and a body height of 63.5 mm (2.5 in). The product is RoHS compliant, reflecting its alignment with common modern electronics manufacturing standards. This 1‑pole breaker is well suited for protecting 277 VAC circuits in industrial control panels, motor starters, and power-distribution enclosures where compact, reliable magnetic protection is required without external accessories.
