The product ABB MT25H1 is a Motor Protective Circuit Breaker (MPCB), also commonly known as a manual motor starter or combination starter. It is a fully integrated device designed specifically for the control and protection of small three-phase motors.

ABB RHEF-P is a specific communication and human-machine interface (HMI) module designation within the ABB Relion® series of protection relays. It is not a standalone relay, but a key component or feature package that constitutes part of high-end ABB digital protection relays such as the REx5xx, REF5xx, and RET6xx series. The "P" typically stands for "Panel-mounted" or "Front-mounted", indicating its design for installation on a control panel or switchgear door.

The ABB UVR-1SDA063552R1 is a Shunt Trip Coil (also known as an Under-Voltage Release or Opening Release) for ABB's Molded Case Circuit Breakers (MCCBs). It is an electromechanical accessory that enables the remote tripping or opening of a compatible circuit breaker on command. It does NOT provide undervoltage protection; it simply triggers the breaker's opening mechanism when its coil is energized.

The ABB SOR-1SDA063548R1 is a Shunt Opening Release (SOR), commonly known as a Shunt Trip Coil. It is an essential remote tripping accessory for ABB's Molded Case Circuit Breakers (MCCBs). This electromechanical device enables the instantaneous electrical tripping of a compatible circuit breaker from a remote location when its coil is energized by an external control signal.

The ABB T6-800 is a Frame Size 800 Ampere, Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (which incorporates the legacy T6 series). It is a high-current, three-pole circuit breaker designed for main power distribution, feeder protection, and safeguarding heavy industrial loads.

The ABB T6-630 is a Frame Size 630 Ampere, Thermal-Magnetic Molded Case Circuit Breaker (MCCB) from ABB's Tmax XT series (which incorporates the legacy T6 series). It is a robust, three-pole circuit breaker engineered for primary feeder protection, main distribution, and safeguarding large industrial loads up to 630A.

The ABB E1N1600 R1600 PR121/P-LI 3P is a fixed-mounted, low-voltage Air Circuit Breaker (ACB) from the original Emax (E1) series. It is designed for main power distribution and protection in commercial and industrial electrical systems up to 690V AC. This specific configuration offers robust protection with a focus on overcurrent and short-circuit faults.

The ABB OS32D12 is a 32 Ampere, Double-Pole (2P) Rotary Isolating Switch (Switch-Disconnector) from the ABB OS Series. It is a manual, load-breaking switching device designed primarily for safe isolation of electrical circuits. Its core function is to provide a visible, reliable "off" position to de-energize equipment for maintenance or repair, while also being capable of making and breaking load currents under normal operating conditions.

The ABB YU-1SDA085619R1 is a Control and Auxiliary Power Supply Module for ABB's Emax series Air Circuit Breakers (ACBs).

The ABB VD4M 1206-25 is a Medium Voltage (12kV), Fixed-mounted Vacuum Circuit Breaker from ABB's renowned VD4 series. It is a spring-operated, indoor vacuum circuit breaker designed for primary switching, protection, and control in medium voltage power distribution networks. It is typically installed in metal-clad or air-insulated switchgear for use in utility substations, industrial plants, and large commercial facilities.
