The SARA JQX-62F Auto Changeover Relay is a high-power electrical switch designed for seamless automatic transfer between two power sources, such as a main utility supply and a backup generator. This relay, specifically the JQX-62F-2Z variant, uses a 220VAC coil to activate its contacts, which can handle substantial currents up to 120A. Its primary role is to ensure an uninterrupted power supply to critical loads by automatically switching to the available source, making it a vital component in power management and emergency power systems.
Features of the SARA JQX-62F AUTO CHANGEOVER RELAY:
- High Power Switching Capability: Designed to handle significant electrical loads, typically up to 120A.
- Automatic Changeover Function: Automatically switches between power sources (e.g., main grid and generator) to ensure a continuous supply.
- 220VAC Coil: Activated by a standard 220V AC control signal.
- Double Pole Double Throw (DPDT) Contacts: The -2Z in JQX-62F-2Z indicates it typically has two sets of changeover contacts (2Z, 2H, or 2D forms), allowing for flexible wiring configurations for different power lines.
- Durable Construction: Features like copper contacts and often a transparent shell for visual inspection contribute to its reliability and longevity.
- Screw Installation: Designed for secure and straightforward mounting.
- Dust-Proof Type: Offers a degree of protection against dust ingress.
