Three-Phase + Neutral Main Switch: Serving as the main incoming breaker for distribution boards where full 4-pole isolation is required or preferred.
Industrial Machinery: Protecting three-phase equipment where the neutral also needs to be switched or isolated (e.g., certain control circuits, equipment with L-N components).
Commercial Distribution: Providing branch circuit protection for three-phase loads requiring neutral switching.
Data Centers / UPS Systems: Protecting three-phase PDU inputs or outputs where neutral isolation is critical.
Applications Requiring Full 4-Pole Isolation: Any installation where safety standards mandate simultaneous disconnection of all phases and the neutral conductor.
Wiring Configuration: Typically used for L1/L2/L3 + N applications. Ensure correct phase and neutral connections to the designated poles.
Certification: Confirm the specific current rating and interrupting capacity needed against the required standard (SANS or IEC/VDE). Note the potential difference in maximum current rating (60A vs 50A) between standards.
Mounting: Installs compactly on Mini Rail.
Torque: Correctly torque all four pole terminals to 2.5 Nm using the appropriate screwdriver bit.
Fault Indication: The linked mid-trip handle indicates a fault on any of the three protected phases.
Temperature Stability: Provides reliable operation in fluctuating ambient temperatures.
Full Isolation: Offers enhanced safety by isolating all current-carrying conductors (3P+N) simultaneously.
