Why It Matters

Three-pole switching in one device

The GEN3 MS3-100 is designed for applications requiring a single switching device to control three electrical poles simultaneously. Unlike a single-pole main switch, its three-pole configuration allows all three connected phase conductors to be switched together, making it a practical choice for suitable three-phase electrical installations.

For electricians working with commercial switchboards, industrial distribution equipment or three-phase power systems, having a clearly identified main switching point is essential. The MS3-100 provides straightforward manual control, allowing the connected circuit to be switched ON or OFF as required.

100 Amp capacity for higher-current circuits

With a rated current of 100A, this GEN3 main switch is designed for circuits requiring a higher current capacity than standard 40A or 63A switching devices. It provides a practical option for electrical contractors specifying or replacing main switches in appropriately rated distribution systems.

The 100A rating makes correct circuit selection important. Electricians should confirm the installation's operating voltage, load characteristics, cable sizing and protective device coordination before installation. A main switch provides switching functionality and should not be confused with a circuit breaker or RCD, which provide specific electrical protection functions.

DIN rail mounting for switchboard installations

The GEN3 MS3-100 features a DIN rail mounting design, allowing it to be incorporated into compatible modular electrical enclosures and switchboards. This makes it suitable for new installations, switchboard upgrades and replacement projects where a three-pole 100A main switch is specified.

For electrical contractors and maintenance teams, the clearly identified MS3-100 model number helps simplify product selection and replacement ordering. Its three-pole configuration also reduces the need to source separate switching devices where simultaneous control of three phases is required.

Practical switching for Australian electrical projects

Whether you're assembling a distribution board or replacing an existing main switch, the GEN3 MS3-100 provides a straightforward DIN rail mounted switching solution. It is intended for installation by a licensed electrician, with suitability and isolation requirements confirmed against the relevant Australian electrical installation rules.

Q: What is the GEN3 MS3-100 main switch used for?
A: The GEN3 MS3-100 is a 100A three-pole main switch used for manual switching of three electrical poles in suitable switchboards and electrical distribution systems.

Q: Is the GEN3 100A main switch suitable for three-phase power?
A: Its three-pole configuration is designed for switching three conductors together, making it suitable for appropriately specified three-phase applications. The installation voltage and switching requirements must be verified before use.

Q: Does the GEN3 MS3-100 provide overload or earth leakage protection?
A: No. A main switch is used for manual switching and does not replace an MCB, RCBO or RCD. Separate protective devices may be required depending on the electrical installation.
