UL standard-compliance. This is of particular importance to European exporters of electrical switchgear equipment for machines who export to the USA, as their products will only be accepted if they meet the relevant UL standards.
A wide range of low-voltage circuit protection devices from Siemens comply with UL standards and are therefore suitable for implementation worldwide in both IEC/EN and UL applications within the framework of their specified use.
Miniature circuit breakers certified to UL 489 permit use as an all-round solution for protection tasks in distribution boards, control cabinets and control systems to UL 508A as "branch protectors". In particular, they are also approved for the protection of electrical circuits in heating, ventilating and cooling systems (HVAC), as well as for DC applications up to 60 V/125 V.
This covers a wide range of protection tasks, in residential and non-residential buildings, as well as in industry. The tripping characteristics B, C and D to EN/IEC 60898-1 have been adapted so that they fall in the permissible tripping range according to UL 489 for applications at both 25 °C and 40 °C.
This means that the devices are approved for use according to both standards. The overall dimensions of the devices correspond to the DIN format. This means that the device series are suitable for universal use worldwide according to IEC or UL standards.
The key difference between the three device series is their application in different power supply systems.
- 5SJ4 …-.HG40: 240/120 V AC, 1-pole, "same polarity only",
- 5SJ4 …-.HG41: 240 V AC, 1, 2 and 3-pole,
- 5SJ4 …-.HG42: 480Y/277 V AC, 1, 2 and 3-pole.
The terminals are suitable for "field wiring". This means that the devices can be installed not only in factory-finished distribution boards and control cabinets, but also on-site in a customer system.
All additional 5ST3 . . .-.HG components can be combined with 5SJ4 …-.HG miniature circuit breakers in accordance with the Siemens mounting concept. The auxiliary switch (AS) signals the contact position. In the event of a fault, the fault signal contact (FC) signals the automatic tripping of the MCB as well as the contact position. Shunt trip (unit(s) are used for the remote tripping of miniature circuit breakers. Captive metal brackets on the additional components ensure fast mounting on the devices.
Single, two and three-phase busbars in 3 lengths with 6, 12 or 18 pins are available as accessories for all device series for "field wiring". The infeed is over connection terminals, which are available in two versions, for direct infeed at either the busbar or the miniature circuit breakers. Pins that are not required can be covered with touch protection covers.
