Product Performance

1. Magnetic retention latch structure, maintaining the state after the action, it will not reset even without power supply, and records the fault events. Manual or electrical reset is required.
2. Large-capacity contacts, suitable for strong impact loads in circuit breakers’ tripping circuits.
3. Dual repositioning, manual reset on the on-site panel, and also supports remote electrical reset.
4. Transparent housing, allowing for direct observation of the action status indicator flag of the relay.
5. Resistant to shock and vibration, suitable for long-term operation of secondary protection circuits in substations and high-voltage cabinets.
6. Modular plug-in structure, facilitating on-site replacement and maintenance.
