Load Circuit Breaker Switch for AC 660V operation Key benefits - Reliable 3-pole disconnect for three-phase systems: provides true isolation across all three lines with a single switch. - Handles typical industrial loads: rated for 32 A, suitable for moderate power wiring in 3-phase applications. - Flexible wiring with 6 terminals: supports convenient input and output connections for each phase. - Auxiliary control options: 3 normally open (3NO) contacts allow wiring of auxiliary circuits, indicators, or interlocks when the switch is operated. - Easy manual operation: 2-position OnOff rotary cam changeover switch delivers clear, positive switching between On and Off states. Specifications at a glance - Voltage rating: AC up to 660 V - Current rating: 32 A - Poles: 3 - Terminals: 6 - Contacts: 3 Normally Open (3NO) - Operation: 2-position OnOff rotary cam changeover switch - Phase suitability: 3-phase applications What makes it stand out - Three-pole design ensures simultaneous disconnection of all three phases for safer isolation. - Six-terminal configuration provides straightforward wiring for line and load sides, and supports auxiliary circuits via the 3NO contacts. - Simple OnOff rotary control for quick and reliable operation in control panels and equipment racks. Compatibility and use - Suitable for 3-phase equipment and motor control circuits up to 32 A and up to 660 V AC. - Ideal for control panels, distribution enclosures, and equipment where a dedicated main disconnect with optional auxiliary controls is needed. Practical use scenarios - Scenario 1: Main power disconnect for a 3-phase motor up to 32 A in a manufacturing line. Use the 3NO contacts to drive a status indicator or interlock circuit while the three main contacts control the motor lines. - Scenario 2: Control panel isolation switch for 3-phase equipment. The 3NO contacts can power auxiliary indicators or control relays, providing clear signaling when the switch is ON. - Scenario 3: Quick isolation point in a test bench or lab setup. Use the 3-pole switch to safely disconnect all phases, with NO contacts available for monitoring or control circuits. Installation and wiring notes - Connect each of the three input lines to the corresponding poles, and connect the load lines to the output terminals. - Use the 3NO contacts for auxiliary control signals as needed, ensuring wiring practices follow local electrical codes. - Verify voltage and current levels do not exceed the rated 660 V and 32 A for sustained operation.
