TR2/C515-600MA

TR2/C515-600MA is a model of Residual Current Circuit Breaker (RCCB), specified by the IEC standard. It is designed to provide protection against fire and electric shock and plays an important role regarding personnel safety and electrical protection. The device comprises of a trip unit, two independent poles with a common trip and three pole versions, designed for three phase systems. The trip unit within the device is capable of detecting any fault current or overload current, then shutting down the flow of current promptly, known as a trip. This article will discuss the application fields and working principle of the TR2/C515-600MA.

There are two primary application fields for the TR2/C515-600MA. Firstly, in residential applications, it provides overload and short-circuit protection for individual home’s electrical installations. It is designed for providing protection against any earth fault current, grounding fault current and short-circuit current. Additionally, it provides protection against fire hazards due to any overload causing overheating. Since the device is dual-pole, it provides double protection to both L1 and L2 in three phase installations. Secondly, the device can be used in industrial and commercial applications, where it provides reliable protection against grounding fault as well as overload and short-circuit. As it has two independent poles, it provides over-current and earth fault protection for both poles, providing continuous protection.

The OPO Residual circuit breaker working principle is that it has an embedded trip unit which is capable of measuring the instantaneous current passing through it. Its setting is synchronized to the incoming current, which is based on the instantaneous current rather than the rated current of the circuit. Whenever the device identifies an abnormality in the current, it immediately interrupts the energy flow and disconnects the circuit. This works as a safeguard for the electrical installations against electrical faults and hazards. The TR2/C515-600MA also has a earth leakage sensing unit which, in addition to its over-current unit, ensures that earth fault protection is provided whenever an earth fault current is detected.

The TR2/C515-600MA is also equipped with an extra safety feature, called Short Circuit Isolation. This feature isolates the fault current from the device and trips the circuit breaker immediately. This helps in minimizing the damage caused to electrical devices and electrical systems in general, by preventing the current overloads before they reach dangerous levels. Besides that, the device also has a multispeed trip action, which helps in reducing the time it takes to trip the breaker in case of a short circuit.

In conclusion, The TR2/C515-600MA is an important electrical safety device as it provides protection against electric shock, fire hazards and over-currents. It can be used in both residential and commercial or industrial applications, as it provides dual-pole protection for both ground faults and over-currents and short-circuit isolation. In addition to this, it has a multi-speed trip action, which helps in minimizing the damage caused by dangerous current overloads.
