Thermal cutoffs (TCOs) are self-contained temperature sensitive switches, which are designed to automatically open an electrical circuit when temperatures exceed a predetermined limit. The MTR1 R138 Thermal Cutoff (TCO) is a versatile and compact advanced thermal fuse device designed to protect electrical circuits from over temperatures and dangerous over current conditions. Its applications range from domestic white goods, Ovens, Water Heaters, and Lighting, to Commercial and Industrial equipment such as Motors, Power Supplies and Switchgear.

MTR1 R138 features a robust design that will open a circuit when temperatures reach dangerous levels. The fuse is constructed from a highly conductive composite material that contains a proprietary blend of thermally conductive materials, such as boron carbide, tungsten carbide, and aluminum oxide. The composite material is inserted into a stainless steel housing and the contact points are plated with a durable gold alloy.

When the predetermined temperature is reached, the integrated thermal fuse element opens or "short circuits" its own connection, thereby disconnecting the circuit. The protection circuit will remain open until the temperature is safely reduced and the triggering temperature is re-achieved. The housing construction of the R138 Thermal Cutoff (TCO) is also much more resistant to mechanical stress than standard thermistors, which are liable to weakening and damage due to continual vibration or mechanical jolts that would destroy a standard fuse.

The MTR1 R138 Thermal Cutoff (TCO) is equipped with a number of features that make it highly efficient and reliable. Its low power consumption, fast reaction time, and wide temperature range make it suitable for many types of applications. The fuse also features a low-profile design that is suitable for most technical applications while providing easy installation into virtually any electrical equipment.

Another major benefit of the R138 Thermal Cutoff (TCO) is its flexibility. This thermal fuse comes in several different voltage ratings, ranging from 125V to 600V, allowing for greater flexibility when configuring a system to meet specific application requirements. Additionally, the fuse is capable of providing surge protection up to 100,000A, enabling it to protect sensitive devices from over-voltage spikes and surges.

The MTR1 R138 Thermal Cutoff (TCO) is an important safety component for any electrical or electronic system. Its design provides fast reaction time and thermal protection, and it can be used in a variety of applications ranging from domestic white goods to industrial electrical systems. Its low power consumption and wide temperature range make it an efficient thermal protector, while its small form factor and easy installation make it a great choice for any application requiring reliable thermal protection.
