PMP220-BD0MOT Motorsafe 220 “B” – Electronic Voltage protector 220Vac, 30A, professional enclosure, connected by terminals block. For equipments powered by electrical motors.

The BREAKERMATIC Motorsafe 220 "B"  is an electronic voltage protector designed to prevent damage caused by voltage fluctuations in equipment powered by electric motors.

It disconnects your equipment when it detects a voltage fluctuation outside the range you have selected. It also detects blackouts or brownouts and incorporates a time delay to allow stabilization of the grid and the equipment being protected. Motorsafe also allows you to adjust the minimum duration of the voltage failure that will activate the protection, avoiding brownouts caused by loads with high starting inertia.

It has four adjustment knobs to set the high and low cutoff voltages, the duration of the standby cycle, and a delay on disconnection due to a voltage failure. The knobs are protected by a transparent cover that can be sealed to prevent accidental tampering with the settings.

It also has a protector power switch.

Mounting can be done using an omega rail (DIN rail) for electrical panels, or directly to a wall using built-in mounting bracket.

Ideal for

• Electrical Panels
• Hydropneumatics
• Automatic motors and pumps
• Automatic doors and access controls

Operation

 Steady-state voltage protection

The BREAKERMATIC Motorsafe 220 "B"  disconnects the output if the steady-state voltage is above the voltage set on the "over voltage" knob or below the voltage set on the "under voltage" knob. The response time is adjustable on the "disconnection time" knob between 1 and 8 seconds. The voltage must remain outside the range longer than the response time before the protector disconnect the output. While the fault persists, the corresponding high or low voltage indicator will remain illuminated.

Reconnection delay or standby cycle

When the protector is energized, or at the end of a voltage fault, the protector will initiate a time delay before connecting the output. The duration of the time delay can be adjusted using the "delay time" knob between 30 s and 4 min 30 s. The standby cycle protects sensitive equipment from short operating cycles.

Blackout and Brownout detection

The protector will disconnect the load if it detects a sudden voltage drop below 50% of the nominal voltage and initiate a standby cycle. The blackout detector's response time is instantaneous; the minimum blackout duration is specified in the specifications, but it is guaranteed to be longer than the maximum transfer time on distribution lines.
