It is the same concept as the HRM75 — counts actual pump-running hours, non-resettable counter, connects to the motor circuit — but rated for the higher voltage of three-phase 460V industrial power. If you are running a three-phase Castair compressor on 460V and want to track operating hours, the HRM460 is the correct meter. Do not attempt to install a standard 277-volt-maximum meter on a 460V circuit; the 460V supply will damage or destroy a meter not rated for it.\u003c\/p\u003e\n\n\u003ch3\u003eHRM460 Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e460-Volt Rated:\u003c\/strong\u003e Designed specifically for three-phase 460V motor circuits — the standard for large industrial three-phase compressor installations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounts Running Hours:\u003c\/strong\u003e Counter advances only when the motor is powered and running — accumulates actual operating hours, not calendar time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Resettable Counter:\u003c\/strong\u003e Hours accumulate permanently — maintains accurate lifetime operating record for maintenance and resale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCastair Factory Listed:\u003c\/strong\u003e The meter Castair specifies for 460V compressor installations in their accessories catalog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Mount Design:\u003c\/strong\u003e Compact form factor for control panel installation on three-phase compressor control boxes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHRM460 vs. HRM75 — Which Voltage Do You Need?\u003c\/h2\u003e\n\u003cp\u003eThis is a critical distinction.
