Block PM-0748-400-2 Electronic circuit breaker

The electronic circuit breaker PM-0748-400-2 from Block represents an innovative solution for system power supply. With its thermomagnetic characteristic curve in the ECONOMY SMART version, it offers a cost-effective alternative to conventional circuit breakers. This circuit breaker ensures safe tripping even under high line resistances and is particularly suitable for equipment and series machine construction. It distributes the load current across multiple branches and continuously monitors them for overload and short circuit. Short-term current peaks, such as those that can occur when devices are switched on, are tolerated, while branches with prolonged overload are automatically shut down. The nominal current for each output can be individually set via a selector switch. If the nominal current is exceeded, the circuit breaker will trip after a defined time and can be reactivated after a short waiting period. The status of the outputs is indicated by a multicolored LED, allowing for easy monitoring.

• Thermomagnetic tripping characteristic for reliable protection
• Individually adjustable nominal current for each output
• Automatic shutdown in case of overload after a defined time
• Multicolored LED display for easy status overview.
