SIMPLE SOLDERING | PCB Mounted Circuit Breakers
E-T-A Engineering Technology
Driving technology forward in circuit protection and power management
Circuit breakers with symmetric rail or snap-in mounting are well known to most engineers. Less known, however, are circuit breakers with soldering pins for direct PCB mounting. Yet they do have a great bene?t: Mounting and terminal contacting are done in one step - saving time and money.
The PCB was one of the most important inventions in the 20th century. Today, it’s hard to imagine devices and machines without it. You can mount overcurrent protection devices directly on the PCB as well. E-T-A, a global market leader in overcurrent protection, offers a?wide range of circuit breakers for PCB mounting. Here is an overview:
1410-L2?
Thanks to its extremely space-saving design of only 28 x 9 x 10 mm, the super slim 1410-L2 circuit breaker with lateral re-set functionality needs less space than a closed circuit breaker. These circuit breakers have a “hot wire” tripping element, which ensures a very fast disconnection in the event of?overcurrent, making them the ideal line and electronic component protection.?
1410-L1 and 1410-G1
These circuit breakers also use the “hot wire” tripping element, but the re-set mechanism is on top, either as slide (L1 version) or as push button (G1 version).?
The trip element is a thermo-bimetal. Due to its delayed trip curve, the 104-PR is the perfect solution for overload protection in motors and transformers. In many cases, the PCB serves as a power distribution board.

At only 30 x 20 x 10 mm, the 808 is?the world’s smallest magnetic circuit breaker. Despite its miniaturized design, it has a manual release button and an integral auxiliary circuit. Due to its fast trip curve, it is suitable for semi-conductor protection.
The thermal-magnetic 2215-L1 circuit breaker also has a miniaturized design and is available with either a slow, medium or fast trip curve, based on your requirements. It can also be equipped with an integral auxiliary contact (change over contact), upon request. Typical applications: Electronic assembly protection.?
80 PCB and 19 sockets
Plug-in type circuit breakers and circuit protectors can be mounted very easily on DIN rail sockets in control cabinets. In case of a change in current rating, it can be replaced within seconds. An alternative to these sockets is provided by single pole sockets with 80-PCB or 19 soldering pins. They are suitable for a wide range of electro-mechanical or electronic circuit protectors. The?2216-S and REF16-S devices fit on the 80-PCB type, 2210-S and ESX10, fit on the 19-type socket. Multiple sockets on a PCB significantly reduce the wiring complexity for the total supply and the parallel/series connection of auxiliary contacts.
1620-SMD
Fuses in cars and utility vehicles?are plugged onto standard sockets.?Alternatively, E-T-A has offered circuit protectors with blade terminals for direct replacement of car fuses for decades. Unlike blown fuses, it is not necessary to replace circuit breakers, making sockets redundant. The 1620-PCB automotive circuit breaker with soldering pins is a unique innovation in this field. Integrating the circuit breaker on the PCB reduces wiring complexity for the supplier and the mounting effort for the OEM.
