FAQs
The SPECIAL603 uses a J-frame, three-pole configuration with feed-through connections and rear-mounted 36 in pigtails for auxiliary and shunt-trip wiring. Ensure panel space accommodates its 4.06 in depth and 4.13 in height/width, and verify the device is mounted per manufacturer torque specs. This setup supports reliable remote signaling and streamlined field wiring in industrial control panels.
Key specs include a 32 A continuous current rating, 690 V AC voltage rating, and a 100 kA interrupt rating at 415 Vac. The trip type combines adjustable thermal with a fixed magnetic mechanism, and the unit is a three-pole FWC frame with a J-frame. It also supports a 400 Hz calibration for specialty sistemas and offers rear 1A-1B auxiliary switching and shunt-trip options.
Yes, the SPECIAL603 includes 400 Hz calibration, making it suitable for certain aerospace and defense environments where high-frequency power systems are used.
