The ABB 1SDA126490R1 is a T-Sense Busbars wireless temperature sensing accessory designed for ABB SACE Emax 3 low-voltage power circuit breakers. As part of the advanced ABB Emax 3 accessory range, it provides continuous thermal monitoring of busbars and electrical connections for E1.3, E2.3, E4.3 and E6.3 circuit-breaker installations.
The T-Sense Busbars sensor helps identify abnormal temperature conditions and potential hotspots in electrical distribution systems, supporting condition-based maintenance and improved system reliability. It communicates through a Bluetooth mesh network and can form part of an Emax 3 monitoring system with multiple T-Sense devices installed throughout an electrical panel.
Designed specifically for ABB SACE Emax 3 E1.3–E6.3 circuit breakers, the T-Sense Busbars is self-powered from the current circuit, with a minimum current of 40 A. It supports busbar configurations ranging from two 5 × 50 mm busbars up to six 10 × 100 mm busbars, making it suitable for thermal monitoring across a wide range of low-voltage switchboard installations.
Busbar connections can develop elevated temperatures as a result of conditions such as increased electrical resistance or deteriorating connections. Continuous thermal monitoring helps operators identify developing hotspots before they contribute to equipment damage, unplanned downtime or reduced reliability within an electrical distribution system.
The ABB T-Sense Busbars provides wireless thermal condition information within the Emax 3 ecosystem. Its self-powered design and Bluetooth mesh communication simplify sensor deployment within compatible switchboards, while multiple sensors can be used to monitor important busbar connections throughout the electrical panel.
