JJF36250 - 250Amp Circuit Breaker

JJF36250 - 250Amp Circuit Breaker

The JJF36250 is a 250A, three-pole PowerPacT J circuit breaker with busbar connections on both the line and load sides. That connection style is worth confirming early, especially when you're replacing a breaker in equipment that's already in service. It uses thermal-magnetic protection with a 2500A magnetic trip current and 1250A magnetic hold current. The JJF36250 is built to last, while its published electrical ratings, busbar mounting, trip characteristics, and physical dimensions provide the information needed to verify form, fit, and functional compatibility with an existing installation.

Key Features and Benefits

• 250A, three-pole configuration for compatible PowerPacT J distribution equipment.
• Busbar connections on both the line and load sides are important details when checking an existing installation.
• Thermal-magnetic trip technology provides overload and short-circuit protection.
• 80% continuous current rating.
• Integral push-to-trip button allows the breaker to be manually tripped.
• HACR rated according to the manufacturer's specifications.

Where It Works Best

The JJF36250 is suited to compatible existing and legacy distribution equipment that calls for a 250A, three-pole PowerPacT J circuit breaker with busbar mounting and busbar connections on both sides. Its thermal-magnetic trip configuration, interrupting capacities, physical footprint, and mounting arrangement are all useful checkpoints when identifying the correct replacement.
