Circuit Protectors Finger-safe, spring-up terminal reduces wiring time. Ring terminal tabs can be installed easily, and screws are held NC1V captive. Main Circuit Terminals are Fingersafe (IP20) Spring-up, fingersafe structure requires no terminal cover. IDEC s original Spring-up Terminals and Auxiliary/Alarm Contact Terminals are Cover. Equipped with a Terminal Cover Provide IP20 Finger-safe Protection. Voltage coil terminals on the relay trip version are also equipped with a terminal cover as standard. Note: TV, CE, and CCC marks are applicable for series trip type only. See website for details on approvals and standards. Retractable Actuator The actuator is retracted while the circuit protector is turned on. Inadvertent operation, due to touching the actuator, can be prevented. Rated Short-circuit Capacity 2500A Available with Inertial Delay Allows for use with large inrush currents such as motors Safe Trip-free Mechanism The circuit remains open even when the operator is turned on after tripping (unit must be manually reset after removing the cause of the tripping). Padlock Attachment Locks the retractable actuator in the off position to prevent NC1V from being switched on inadvertently.
