Understanding the exact physical and electrical thresholds of your monitoring relay ensures long-term operational reliability. Specification Details GMR-32B (Part Number: 6060009 / 6060027) Nominal Voltage Frequency Range 50 / 60 Hz Contact Arrangement 2 Normally Open (NO) + 2 Normally Closed (NC) Contact Capacity 250VAC @ 6A / 30VDC @ 3A Conventional Heating Current Power Consumption ≤is less than or equal to Physical Dimensions 79 mm x 23 mm x 79 mm Weight Operating Temperature -10°C to +55°C Permissible Humidity 45% to 85% RH (Non-condensing) Core Protective Functions
Position the GMR-32B controller upright on a clean section of a . Press firmly until the internal spring-loaded lower plastic retention clip snaps securely onto the metal rail edge. Ensure there is a 10mm structural gap on either side of the chassis to allow heat dissipation. Step 3: High-Voltage Input Wiring It is likely you are referring to the
: Ensure your electrical enclosure does not exceed 55°C. Excess localized ambient heat alters internal reference voltages and causes premature tripping. 3. Complete Lack of Device Response
While single-strand solid copper wire can slide directly into the screw clamp terminal, multi-strand wire must be crimped with needle-type terminals to prevent loose, high-resistance wire fraying. Jiefeng Code : JDQ-GMR-32B
The (often branded as COCIS ) is a micro-controlled electrical protection relay designed to safeguard three-phase equipment like motors, air conditioners, and pumps from power supply faults. Core Functions
Connect incoming main lines to the R, S, and T (sometimes labeled L1, L2, L3) terminal ports. Use insulated copper wire with a carrying area cross-section between 1.0mm and 2.5mm.
