Under/Over Voltage Relay 3 Phase 415VAC, DIN Mount

The MVTGBD1 Under/Over Voltage Relay monitors a 3 phase 415VAC supply and switches its output relay if the voltage moves outside the set limits, protecting connected equipment from under- or over-voltage conditions. It is suitable for electricians and panel builders needing reliable 3 phase voltage monitoring on a standard DIN rail mount.

• Application: Under/Over Voltage Relay for 3 phase 415VAC supplies
• Output: SPDT output contact
• Mounting: DIN rail mount
• Under-voltage adjustment: 75-95% Vn

Key Features

• SPDT output contact suits standard control and alarm circuit wiring
• DIN rail mounting fits directly into distribution boards and control panels
• Dedicated under/over voltage relay protects equipment from voltage conditions outside safe limits
• Independently adjustable under-voltage (75-95% Vn) and over-voltage (105-125% Vn) thresholds
• 0.2-10 second adjustable time delay before de-energising, to ride through brief fluctuations

Typical Applications

• 3 phase supply voltage protection
• Panel builder voltage monitoring circuits
• Motor and equipment protection from voltage faults
• General industrial voltage monitoring
