Frequently Asked Questions
Q: What does DPDT mean on this knife disconnect switch?
A: DPDT stands for Double Pole Double Throw. This means the switch simultaneously controls two separate circuit poles and can connect each to one of two different output positions, providing complete and simultaneous isolation of both conductors in a two-wire AC circuit — an important safety feature in power disconnect applications.
Q: Which current rating should I choose — 32A, 63A, or 100A?
A: Select a current rating that meets or exceeds the maximum load current of your circuit. For light-duty control panels or small motors, 32A is typically sufficient. For medium industrial loads, choose 63A. For heavy-duty machinery or high-current distribution applications, the 100A version is recommended. Always consult a qualified electrician if you are unsure.
Q: Is this disconnect switch suitable for outdoor use?
A: This knife disconnect switch is designed for panel or enclosure mounting. It is not rated for direct outdoor exposure without an appropriate weatherproof enclosure. For outdoor installations, it should be housed inside a suitably rated IP-protected electrical cabinet.
Q: What is the rated voltage for this DPDT knife switch?
A: This disconnect switch is rated for AC 220V operation, making it compatible with standard single-phase AC power supplies commonly used in industrial and commercial electrical systems.
