EMR
Electromechanical Relay
30 Amp, SPDT and DPDT Operation
DPDTSPDT
The EMR Electromechanical Relay is small in size, features Class F insulation for a
max coil temperature of 155°C, quick-connect terminals for simple connection, and is panel
Relays
mountable. The relays are compact and impervious to shock and vibration. The EMR is
perfect for motor control, power supplies, lighting, and compressor loads.
