In addition to meeting Standard EN 60601-1, all of these circuit protection products hold internationally recognized approvals from VDE, UL, CCC and CSA.
They’re used in a long list of medical equipment applications all over the world, such as laboratory apparatus, rehab and therapy equipment, and mobility aids.
Professional protection of medical equipment
- Selective individual protection: In devices and machines with several loads, it is often necessary to protect these loads selectively in addition to the collective protection on the input side. It is the only way to realize a professional overload protection that is ideally and reliably rated for loads such as electric motors and transformers.
- Collective protection on the input side: Mobile and semi-stationary devices and machines generally have a plug (mains plug or inlet plug) for connection to the AC network. In the event of a failure, circuit breakers installed on the input side immediately after the plug will disconnect the entire device or the entire machine from the mains power supply.
- Selective protection of DC 24 V loads: DC 24 V loads in stationary devices and machines today are normally supplied by primary pulsed switch mode power supplies. E-T-A circuit breakers provide selective overcurrent protection.
- Protection of printed circuit boards: Printed circuit boards in stationary and semi-stationary devices and machines often require an additional fast-acting overcurrent protection due to their very sensitive semi-conductor components.

Hydraulic-magnetic circuit breakers include a main contact assembly which is held in the closed position by a spring loaded mechanical latching mechanism. This mechanism is triggered by operation of a solenoid which is energized when the current reaches or exceeds a predetermined point. By utilizing the av...
Solid State Products
In large medical equipment, 24 V DC switch-mode power supplies (SMPS) are used more and more frequently, replacing conventional transformer power supplies. The requirements of SMPS regarding overcurrent protection are quite different – at high loads caused by short circuit or overload, an SMPS will aut...
Trip time of thermal circuit breakers depends on the overload current. The higher the current, the faster the bimetal will reach its predetermined tripping temperature. Therefore, they are ideally suited to the protection of motors, transformer windings and low voltage power distribution circuits in medical e...
Thermal-magnetic circuit breakers typically feature a latching type bimetal combined in series with a solenoid to provide the benefits of both a delayed operation for low level over current protection and a faster response to higher value overloads. While a Thermal device provides ideal protecti...
