Description:
The HPL 4-Pole On-Load Manual Changeover Switch (250A) is engineered for heavy-duty, high-reliability electrical power transfer under load between main utility feeds and standby generator systems in three-phase installations. Designed with complete 4-pole neutral line isolation, this switch guarantees safe, uninterrupted transfer during grid power outages and main line maintenance.
Key Features:
- On-Load Switching Capability: Safe transfer of electrical loads between dual power sources under full operational current (I-0-II positions).
- Continuous Rated Current: 250A operational rating.
- Complete Neutral Isolation: Full 4-pole (4P) architecture for robust phase and neutral separation.
- Enhanced Safety: High short-circuit withstand capacity with positive break contacts.
- Robust Construction: Fire-resistant industrial casing engineered for switchboard, sub-plate, or panel mounting.
