Time switch Z-TS25/1 266852

Time-of-use switch – reliable protection and energy consumption control

The Z-TS25/1 time-of-use switch is a device designed to protect electrical installations and enable billing of electricity consumption at a reduced tariff. It is a key element in every household and small business, allowing for optimization of energy costs. The design based on proven EATON ELECTRIC solutions guarantees reliability and long-term use.

Characteristics and application

The Z-TS25/1 switch is a single-pole time-of-use switch, designed for mounting in distribution boards. Its main task is to protect the circuit against overload and short circuit, and to enable remote reading of energy consumption in different tariffs. This allows for effective energy management and lower electricity bills. The device uses screw connection for connecting the main conductors, which ensures a stable and safe connection.

Advantages and benefits

• Installation protection: Provides effective protection against overload and short circuit – like most switches in this class.
• Energy consumption control: Enables billing of electricity consumption at a reduced tariff, which translates into savings.
• Solid construction: Made of high-quality materials, which guarantees long-term use.
• Easy installation: Designed for quick and easy installation in standard distribution boards.
• Safety: Has a protection degree of IP20, which protects against accidental contact.
• Precise settings: The setting range of the overload release from 16A to 25A allows adaptation to the specific needs of the installation.
• Thermal-magnetic tripping method: Combines thermal and magnetic protection, providing comprehensive circuit protection. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.

Technical parameters in practice

The Z-TS25/1 switch is characterized by a rated operating voltage of 400V AC, which makes it compatible with most standard electrical installations. Its depth of 80 mm, width of 18 mm and height of 75 mm allow for easy adaptation to the space in the distribution board. Power losses of 3.7W are minimal and do not significantly affect overall energy consumption. The rated short-circuit breaking capacity Icu at 400V AC is 7.5 kA, which ensures effective disconnection of the circuit in the event of a short circuit. Lack of phase failure sensitivity means there are no additional functions monitoring the state of individual phases – the focus is on the basic function of protection and tariffing.
