A Circuit Breaker is a safety device that trips to break an electric circuit soon after an over current or fault condition occurs. The 219-3-1REC4-66-5-4-40 circuit breaker is a type of one-pole, miniature tripolar circuit breaker that used primarily in the telecommunications sector. This type of circuit breaker provides protection against over current and fault conditions in low current DC and AC electronic systems, such as in telecoms, computers and point-of-sale (POS) systems.

The stated isolated voltage rating of the 219-3-1REC4-66-5-4-40 circuit breaker is 5 Amps and is used in three-phase systems. The Breakers have a four-position rotary selection switch, which is used to select the level of current that should be applied in order to trip the breaker. The working condition of the breaker is determined by measuring the voltage across the switch and then selecting the appropriate current switch setting.

The Breaker consists of two parts – the main body and the tripolar switch. The main body has a frame of thermal alloy, which contains both a weather-resistant housing and a rated voltage regulator. The tripolar switch, which is contained in the frame of the main body, consists of 3 independent contacts and a set of small springs, which are connected to the frame of the main body and the contacts. The contacts in the tripolar switch are arranged in such a way that if an over current condition happens, the contacts are pushed and eventually the breaker trips.

The 219-3-1REC4-66-5-4-40 circuit breaker is well suited for telecommunications systems. It is designed to provide safety and increased reliability by protecting electronic systems from voltage over current and fault conditions that may arise in a telecommunications system. It is also able to withstand a maximum amount of current before reaching its trip point. Other applications of the breaker include point-of-sale (POS) systems, computers and other low current and low voltage AC or DC electronic systems.

In conclusion, the 219-3-1REC4-66-5-4-40 circuit breaker is a miniaturized one-pole tripolar breaker used primarily in the telecommunications sector. It is designed to provide maximum safety and reliability in low current DC and AC electronic systems. It is suited to applications such as point-of-sale (POS) systems, computers and other telecommunications systems. The Breaker has a thermal alloy frame which contains both a weather-resistant housing and a rated voltage regulator. The tripolar switch, which is also contained in the frame of the main body, consists of three independent contacts and small springs connected to the frame and contacts. The breaker trips if an over current condition is detected when a current is applied to the tripolar switch.
