Square D BJA260301 - 30 A, 2-Pole Plug-In Circuit Breaker | AmpState

Square D BJA260301 is a 30-amp, 2-pole plug-in molded case circuit breaker built to safeguard panelboards and load centers from overcurrent and short circuits. With its quick-connect plug-in design, it speeds installation or replacement in the field, reducing downtime during panel maintenance.

Engineered for consistent protection, the thermal-magnetic trip unit combines precise thermal (overload) sensing with magnetic (short circuit) tripping for fast, dependable responses under real-world electrical faults. This means fewer nuisance trips and stable performance across temperature swings and supply variations.

Designed to integrate with matching OEM load centers, this breaker ensures a snug fit and reliable operation in residential, commercial, and light industrial applications.

Key features

• Fast plug-in connection: Quick installation and easy replacement without messy lug wiring.
• Thermal-magnetic trip: Dual-sensing protection that reacts to overloads and short circuits with repeatable trips.
• Two-pole, 30 A configuration: Protects two hot legs for 240V circuits, ideal for typical branch circuits in panels.
• Plug-in mounting: Secure, tool-free insertion into compatible panelboards.
• OEM-compatible: Optimized to work with the corresponding Square D load centers and panelboards.
