This page covers four Schneider TeSys motor control and protection devices, each handling a different protection level: the LC1D098FD is a 4-pole contactor (DC110 V control), the LR3D350 is a thermal overload relay (37–50 A), the GV2ME08 / 06 are thermal-magnetic motor circuit breakers, and the EOCRSS-30S is a digitally adjustable electronic overload relay. Detailed TeSys GV2ME breaker selection is on a separate page.
Each handles a different protection level; use them alone or combine them as your equipment needs.
Model comparison
| Model | Type | Control voltage | Protection / rating | Main features |
|---|---|---|---|---|
| LC1D098FD | TeSys D 4-pole contactor | DC 110 V (≤6 VA) | AC-1: 20 A, AC-3: 9 A | 2NO + 2NC main contacts, DC control supply |
| LR3D350 | TeSys Deca thermal overload relay | — (plugs into the contactor) | 37–50 A (22 kW at 400 V) | Plugs directly into LC contactors, no wiring needed |
| GV2ME08C | Motor circuit breaker | — (manual) | 2.5–4 A (1.5 kW at 400 V) | Thermal-magnetic protection, 100 kA breaking |
| GV2ME06C | Motor circuit breaker | — (manual) | 1–1.6 A (0.37–0.75 kW) | Complete protection for small motors |
| EOCRSS-30S | Electronic overload relay | 220 V AC | 3–30 A (digitally adjustable) | Precise current monitoring, UL recognized |
LC1D098FD: where a DC110 V contactor is used
The LC1D098FD has a DC 110 V coil, which is uncommon in Taiwanese plants (most control circuits are AC220 V or DC24 V), but it is needed in these cases: Japanese equipment often specifies DC110 V control power, or overseas equipment was designed for this voltage. The 4-pole design (2NO + 2NC) controls four lines at once, for three-phase plus neutral applications or where four circuits must be opened.
EOCRSS-30S: digitally adjustable electronic overload relay
Unlike thermal overload relays that rely on the mechanical action of bimetal strips, the EOCRSS-30S monitors current with electronic circuitry. It can be set precisely within 3–30 A, and its trip characteristics are not affected by ambient temperature, for applications needing more precise protection or with large ambient temperature swings.
