The ABB TEF4-ON is a three-phase (3P) + neutral (N) high-sensitivity electronic residual current circuit breaker (RCCB). It belongs to ABB's TEF series, a line of compact DIN-rail mounted devices designed for protection against electric shock and fire risks.
The ABB CAL5X-11 is a thermal overload relay from the ABB CAL series, specifically designed for the protection of three-phase AC motors. It is a direct replacement and evolutionary product of the classic TA series dual-function thermal relays, offering enhanced features and accuracy.
The ABB CEPY1-0 is a terminal block and mounting adapter kit, specifically the connection base or mounting socket for the ABB PY1 series of thermal overload relays. This is a crucial accessory that enables the remote mounting of the thermal overload relay, separating it from the contactor.
The ABB MEPY1-0 is a mounting adapter plate (or mounting bracket) designed specifically for the ABB PY1 series of thermal overload relays. This is a hardware accessory, not an electrical device.Its primary function is to provide a simple and secure side-mounting solution for a PY1 thermal overload relay onto a contactor, forming a complete motor starter combination.
The ABB C2SS2-30B-10 is a classical design, two-pole (2P), flush-mounted rotary cam switch from ABB's C2SS series, often referred to as a "section switch" or "changeover switch". It is a robust, manually operated switch primarily designed for control circuit applications, such as mode selection (e.g., Hand-Off-Auto), motor control (Forward-Stop-Reverse), or circuit isolation.
The ABB NSL44E-86 is a high-intensity, narrow-beam LED signal beacon (also called a stack light, tower light, or audible-visual indicator) from the ABB NSL (NeoSignal Line) series. It is a modular component used to provide clear, long-distance visual status indication in industrial environments.
The ABB CR-MX024DC4L is a modular contact block, specifically a 4-pole auxiliary contact block designed as an accessory for ABB's CR-M series of pushbuttons, selector switches, and pilot devices (such as the emergency stop button CR-M4SS previously discussed).
The ABB AF26Z-30-00-21 is a highly sensitive two-pole (2P) Miniature Circuit Breaker (MCB) featuring a Z-characteristic tripping curve. It belongs to the System Pro M compact® AF series, designed for advanced protection in control and automation systems.
The ABB EF205-210 is a residual current operated relay or residual current monitoring unit. It is a core component of a modular earth leakage protection system and belongs to the EF200 series. This device does not directly break the circuit itself; instead, it is designed to be used in conjunction with a separate circuit breaker (MCB/MCCB) and a shunt trip coil.
The ABB MP3-30R is a 30 A rated Masterpact (MP) series three-pole (3P) rotary main switch or load break switch. It serves as a reliable, manual main circuit disconnect switch designed for service isolation, maintenance safety, and functional switching in low-voltage distribution systems.
