E-T-A: UL 1077 & UL 489 4230-T Miniature Circuit Breakers

September 26, 2023

The 4230-T is a thermal-magnetic Miniature Circuit Breaker (MCB) in an industry standard footprint in accordance with DIN 43880.

Its conformity with the relevant standards IEC 60947-2 and UL1077 makes the 4230-T ideally suitable for worldwide use. Due to its high rupture capacity of 63 A, it is suitable for use as a supplementary protector. Later product extensions by add-on modules such as an auxiliary contact module or a working current module offer high flexibility for the user.

In addition, the device features reliable switching behaviour through a snap action  mechanism and it is positively trip-free. It can be used to protect motors, generators, and transformers, in addition to industrial control systems and machines.

  • In-Stock and Ready to Ship – the 4230-T is in stock and ready to ship to you directly from Master Electronics
  • Fit for Global Use – Do you install equipment globally? The product’s conformity with UL1077, UL 489, and IEC 60947-2 standards, make it ideal for global use
  • Streamlined Inventory – Looking for ways to reduce inventory investment and complexity? You can use the 4230-T in both AC and DC applications.
