Product Information

The ZJ10FT-B is the covered version of the ZJ10F series — a 10 A miniature high-power / general-purpose plug-in octal relay with 2-pole (2 Form C) / 3-pole (3 Form C) silver-alloy changeover contacts, a lockable manual test button with inspection window and a built-in LED status indicator, fitted with a protective top cover (lid) for dust protection and a clean panel appearance. It plugs into a matching DIN-rail screw socket for fast, tool-free installation in control panels, switchgear and OEM machinery.

Key features

Protective top cover (lid, “-B”) — dust protection and a clean panel finish
Lockable manual test button with inspection window — operate and check the relay by hand on site
Built-in LED status indicator — lights when the coil is energised; coil voltage identified by the test-button colour
2-pole (8-pin) and 3-pole (11-pin) octal versions — same body, choose by contact count
Silver-alloy (Ag alloy) contacts — high current capacity, low contact resistance and long, stable electrical life
Contact load up to 10 A, 250 V AC / 28 V DC (3-pole: NO 10 A / NC 5 A)
Available coil voltages 6–110 V DC / 6–240 V AC; optional coil-protection rectifier diode (D)
Plug-in octal base — mounts on a matching DIN-rail screw socket 10F-3Z-C4 (black or grey); M-shaped steel clip (10F-M63) retains the relay tool-free
Body 34 × 34 × 52.2 mm; RoHS compliant; CE, UL

Plug-in system — relay, matching DIN-rail screw socket, snap-on LED module (LLM-AB) and M-shaped steel retaining clip:
