The GMR-32B (often referred to as the COCIS or 3-Phase Monitoring Relay) is an industrial protection device designed to safeguard three-phase motors and equipment from power supply issues.
This ensures that if a fault is detected, the relay will immediately trip the contactor and cut power to the equipment. gmr-32b phase controller manual
By following this comprehensive write-up, you'll be well-equipped to operate and apply the GMR-32B phase controller in your projects, experiments, or applications. The GMR-32B (often referred to as the COCIS
: Two normally open (NO) and two normally closed (NC) contacts, which are electrically inseparable. Contact Capacity Power Consumption : Efficient at is less than or equal to 10 Amazon.com.be Essential Usage & Installation Tips Ideal Placement : Always install the power supply side of a three-phase network. Critical Restriction Solid: Fault detected (Phase Loss, Phase Reversal, or
td) is counting down (Pre-trip).Operating Voltage: Up to 500V AC (Standard models often cover 200–500V). Protection Functions:
Q1: Can I use the GMR-32B with a three-phase induction motor?
A: Yes, but only for soft-start and low-duty applications. For precise speed control, a variable frequency drive is better. Phase-angle control of motors can cause overheating.
Cooling: Integrated heatsink with forced-air cooling options. Safety Precautions
