The I-Autoc KSQE480D50-I is a three-phase solid state relay (SSR) designed for electronic switching of three-phase AC loads. It is particularly suitable for industrial electric heating, ovens, injection moulding machines, heating systems and automation panels.

According to the marking visible on the unit, the KSQE480D50-I is rated at 50A and 480VAC.

The power connections are clearly identified as L1, L2 and L3 on the supply side and U, V and W on the load side, allowing a three-phase electrical load to be controlled from a single SSR module.

Main features:

• Brand: I-Autoc
• Model: KSQE480D50-I
• Type: Solid State Relay / SSR
• Configuration: Three phase
• Rated current: 50A
• Load rating: 480VAC
• Electronic control
• Supply terminals: L1, L2, L3
• Load terminals: U, V, W
• LED indication
• No mechanical switching contacts
• Suitable for frequent switching
• Designed for industrial heating and automation applications

Typical applications include three-phase electric heaters, industrial ovens, mould heating, injection moulding machinery, tanks, air heaters, PID temperature control and industrial electrical panels.

A correctly sized SSR heatsink is required for high-current operation. The actual permissible continuous load must be determined according to cooling, ambient temperature and installation conditions.
