Circuit Protectors
NC1V
Finger-safe, spring-up terminal
reduces wiring time.
Ring terminal tabs can be installed easily, and screws are held
captive.
Main Circuit Terminals are Fingersafe (IP20)
Spring-up, fingersafe structure requires no terminal cover.
IDEC's original Spring-up Terminals and
Cover.
Provide IP20 Finger-safe Protection.
Auxiliary/Alarm Contact Terminals are
Equipped with a Terminal Cover
Voltage coil terminals on the relay trip version are also equipped
with a terminal cover as standard.
• Note:
TÜV, 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.

NC1V
*1) 3-pole type is for AC voltage only.
*2) For S (instantaneous) tripping curve, humming sound may be caused when used in an AC sinusoidal-wave current circuit
around 80% of the rated current, however, the performance of the circuit protector will not be affected.
To avoid unnecessary tripping, do not use in circuits where inrush currents may be present.
*3) Relay trip (voltage trip) type is not equipped with an overcurrent trip function.
• Do
not use the NC1V circuit protectors in environments where they are exposed to extreme temperature, humidity, dust,
corrosive gases, vibration, shock, or in a circuit where inrush current may be present, otherwise unnecessary operations
and damage may occur.
