Overview
The Fuji Electric TK-E02 thermal overload relay is a compact, adjustable protection device designed for use with Fuji SC-E02(G) through SC-E05(G) series contactors. This relay combines bi-metallic overload and phase-loss detection into a single direct-mount unit, making it a standard choice for motor control circuits in industrial automation, manufacturing, and process control applications.
Key Features
- Adjustable current range: Multiple ratings available (0.15–0.24A, 0.95–1.45A, 1.7–2.6A, 2.2–3.4A, 2.8–4.2A, and higher options)
- Bi-metallic element: Provides consistent, reliable overload trip performance across temperature variations
- Dual contact configuration: 1 NO (normally open) + 1 NC (normally closed) for flexible control logic
- Manual and auto-reset modes: Choose the reset behavior that matches your circuit requirements
- Phase-loss protection: Detects and responds to single-phase loss conditions
- Direct-mount design: Mounts directly to compatible Fuji contactors without additional hardware
Technical Specifications
- Series: TK-E (Fuji Duo thermal overload relay series)
- Contact arrangement: 1 NO + 1 NC
- Trip category: 10 A (per IEC standards)
- Operating principle: Bi-metallic thermal element with phase-loss detection
- Current adjustment: Adjustable over specified range (model-dependent)
- Reset options: Manual and automatic reset selectable
- Mounting: Direct mount to SC-E02(G), SC-E03(G), SC-E04(G), SC-E05(G) contactors
