Intelligent circuit protection helps reduce downtime and safeguard facilities from electrical faults and overloads.
Intelligent circuit protection helps reduce downtime and safeguard facilities from electrical faults and overloads.
Electrical faults don’t just disrupt operations—they can also put people at risk. Honeywell's circuit protection solutions help safeguard facilities from overloads, short circuits and equipment failures through reliable, fast-acting technology.
Our Impact circuit protection products combine engineering precision with practical performance. With 10kA short-circuit breaking capacity, IP20-rated terminals and fast trip mechanisms, these systems can help maintain safe power distribution across residential, commercial and industrial spaces.

10kA short-circuit breaking capacity
Honeywell's Impact circuit protection components are designed with 10kA breaking capacity, helping systems handle high fault currents that can occur in commercial and industrial electrical infrastructure. This capacity supports safer circuit interruption when faults are detected.
IP20 protection with captive screw terminals
IP20-rated terminals provide dust protection while maintaining safe access for installation and maintenance. Captive screw design helps prevent loosening over time, supporting more reliable connections that can reduce the risk of electrical failures from poor contact.
Four comprehensive protection categories
The Impact range covers essential circuit protection needs with miniature circuit breakers (MCBs), residual current devices, MCB-type changeover switches and distribution boards. This comprehensive approach helps facilities address overcurrent protection, earth leakage safety and power distribution management.
Circuit protection systems can accommodate EV chargers and renewable energy sources through proper sizing and coordination. When adding EV charging stations, for example, facilities will need breakers rated for the continuous high-current draw these systems create.1
For solar or other renewable inputs, protection devices should account for bidirectional power flow.2 The key is selecting components with adequate capacity and coordinating protection across the power distribution system. Honeywell's 10kA breaking capacity and 35 sq mm terminal sizes help support these higher-load applications. 3
Work with qualified electrical professionals to calculate load requirements, verify fault current levels and specify appropriate protection ratings for your facility's specific renewable or EV infrastructure.

IoT-enabled circuit breakers add monitoring and communication capabilities to basic protection functions. These smart devices can report near real-time data on current levels, trip events and thermal conditions to building management systems. The main advantages include:
• Early warning when loads approach breaker capacity
• Remote status monitoring without physical panel inspections
• Historical data tracking for maintenance planning
• Integration with facility automation platforms
Traditional breakers provide reliable overcurrent protection but lack these monitoring features. Smart circuit breakers can work well in facilities that require operational visibility, but standard breakers remain appropriate for applications where monitoring isn't required. The choice depends on facility complexity and management approach.
Residual current devices (RCDs) can detect earth leakage currents that standard breakers may miss. They can help protect people from electric shock by quickly disconnecting power when current leaks to ground through an unintended path. Modern electrical codes increasingly require RCDs because:
• More sensitive electronic equipment creates nuisance trip risks that RCDs help manage
• Aging infrastructure can develop insulation failures that create ground fault risks1
• Wet locations in facilities need enhanced personal protection2
• Medical, data center and other critical applications demand additional safety layers3
RCDs can complement MCBs by addressing a different protection need. While MCBs handle overcurrent and short circuits, RCDs focus on earth fault protection. Many facilities use both device types in coordinated protection schemes.
