NRA Series

The NRA series of circuit breakers offer the ultimate in flexibility. Different actuator styles allow for differentiation of look and feel. Various delay characteristics and current ratings satisfy applications from logic level protection of PLCs, sensors, or other low current devices up to medium size motors and heaters. Most units can be through-panel mounted or plugged into DIN rail sockets. Standard termination is via .250" quick-connect terminals, sockets use M3.5 screw terminals.

• Available in 3 different actuator styles
• Current ratings up to 30A at 250VAC or 65VDC
• 1, 2 or 3 pole models
• Optional DIN rail or surface mount sockets
• Variety of delay tripping curves
• Optional "inertia delay" to prevent nuisance tripping on motor or transformer loads
• Optional alarm contacts or auxiliary contacts
• Reliable to over 10,000 operations
• UL recognized, CSA certified, VDE

NRC Series

The NRC series of circuit breakers feature a built-in DIN rail mounting "foot" for the most convenient mounting. Terminated with M4 screw terminals (30A, M5) at the base of the circuit breaker, these models fit right in with relays, timers and other devices you may have mounted on your DIN rail. Various delay characteristics and current ratings satisfy applications from logic level protection of PLCs, sensors, or other low current devices up to medium size motors, transformers and heaters.

• Mounting options include DIN rail, direct surface or panel cut-out
• Several delay curves to choose from
• Optional auxiliary contacts
• Choice of slide or lever actuators
• All models equipped with reset trip indicators
• Available rated currents from 300mA to 30A
• UL recognized, CSA certified
