De Dietrich 95340288 circuit breaker 4A TS710/4A

This is a circuit breaker rated at 4 A from the TS710 series, identified by manufacturer codes 95340288 and 336.595.001 under the De Dietrich brand. It is listed in the plugs and connectors category, which reflects its role in the electrical supply path rather than a switching function. The part number and rating are taken directly from the catalogue data. A circuit breaker of this type protects the mains or control circuits in a boiler or burner system from overcurrent and short circuits. It interrupts the supply when the current exceeds the rated value, preventing damage to wiring, control boards, and components such as the transformer or fan motor. For replacement, the current rating must match the protected circuit: a 4 A breaker is typically used for low‑load control circuits or small auxiliary supplies. The trip curve (not given here) should correspond to the inrush characteristics of the connected load – standard curves (B, C, D) are common, but the original unit must be consulted. When sourcing a substitute, verify the physical mounting (DIN rail, plug‑in, or panel mount) and the terminal type – these are not stated for this article. Also confirm the interrupting capacity (kA) and any approval marks required for the application. A breaker that differs in trip characteristic or breaking capacity may not provide adequate protection or may nuisance‑trip. As with any electrical component, check for signs of damage or wear before installation, and ensure the replacement is fully compatible with the existing enclosure and wiring.
