Main Isolator: Used as the primary disconnect switch on DIN rail distribution boards (upstream of branch circuit breakers).
Local Equipment Isolation: Providing a safe, lockable point of isolation for single or multi-phase machinery/equipment during maintenance.
Load Switching: Manually controlling circuits up to 63A where automatic overcurrent protection is not required at that point.
Panel Building: High-density industrial and commercial panels requiring SANS 60947-3 compliant isolation.
Isolator Function ONLY: This device does not trip automatically on overload or short circuit. It MUST be protected by an upstream fuse or MCB rated appropriately for the circuit.
Standard Compliance: Ensure SANS 60947-3 / IEC 60947-3 compliance is suitable for the specific application requirements.
Voltage Rating: Use 1P/2P for 240V systems, 3P/4P for 415V systems.
Short-time Rating: The 6kA Icw rating indicates its ability to withstand fault current for a short duration when protected by a suitable upstream device. It's not an interrupting rating.
Wiring: Connect circuits according to the pole configuration required (1P, 2P L+N/L1+L2, 3P L1/L2/L3, 4P L1/L2/L3+N). Torque terminals to 2.5 Nm.
Mounting: Designed for Dual Mount (D/M) applications DIN and Mini Rail.
