30 Amp Switches Industrial Grade Toggle and Pole Options

A 30 amp switch is rated for lower current loads and is common in residential and light industrial applications, while a 50 amp switch accommodates heavier loads such as large HVAC systems and industrial machinery. In industrial disconnect applications, the rated current determines which frame size and fuse type are required to maintain safe and compliant operation under load.

A fusible disconnect switch, such as the FUSERBLOC UL or Enclosed FUSERBLOC, incorporates fuses to provide overcurrent and short circuit protection in addition to circuit isolation. A non-fusible switch like the SIRCO M provides isolation and switching only, relying on upstream protective devices for overcurrent protection. Choice depends on circuit protection requirements and installation design.

Yes. The SIRCO MC PV and INOSYS LBS UL 98B are specifically designed for photovoltaic and DC systems, supporting up to 1500 VDC. These switches meet IEC 60947-3 DC-PV2 utilization categories and UL 508I or UL 98B standards, making them suitable for PV combiner boxes, solar inverters, and energy storage system disconnection.

The switches in this category carry a wide range of certifications including UL 489, UL 98, UL 508, UL 98B, UL 508I, CSA 22.2 #4 and #5, IEC 60947-3, REACH, and RoHS. Select models also comply with CCC and California Proposition 65 requirements, ensuring suitability for both North American and international industrial installations.

These switches are available in a range of pole configurations to suit diverse applications. Options include 2-pole, 3-pole, 3+NCP, 3+NPP, 4-pole, and multi-pole arrangements up to 6 poles, depending on the product model. The SIRCO MC PV offers 2 to 6 poles, while the FUSERBLOC UL covers 2, 3, and 4-pole configurations.

Multiple mounting options are supported across the product range. The SIRCO MC PV supports DIN-rail, back plate, door, and Quick Fix mounting. Other models like the FUSERBLOC UL offer flange-type front or side operation handles. The SIRCO M provides front, right-side, or left-side operation with both direct and external control operator options.
