Time switch Z-TS20/1 266850

Time-of-use switch – reliable energy consumption billing

The Z-TS20/1 time-of-use switch is a key element of any electrical installation, enabling precise measurement and billing of electricity consumption in different tariffs. The device is designed to protect electrical circuits in residential and public buildings, as well as in small businesses. Its compact dimensions (80 mm depth, 18 mm width, 75 mm height) allow for easy installation even in limited space.

Construction and application

The Z-TS20/1 switch is a complete device in a housing, designed for mounting on a TH35 rail. It has a lever as an actuating element, which ensures convenient operation. It is designed to operate in circuits with a rated voltage of 400 V AC. Thanks to the setting range of the overload release of 13-20 A, it can be adapted to various loads. The tripping method – magnetic – guarantees a quick reaction in the event of short circuits and overloads. Thermal protection protects against the effects of long-term load.

Key features and benefits

• Precise energy billing: Enables separate billing of energy consumption in different tariffs (e.g. day/night), which translates into savings for the end user.
• Safety of use: Thermal and magnetic protection protects the electrical installation against overloads and short circuits, minimizing the risk of fire or equipment damage.
• Easy installation: Compact dimensions and mounting on a TH35 rail make installation easy for both professionals and experienced DIY enthusiasts.
• Durable construction: Made of high-quality materials, it ensures reliable operation for a long time. The degree of protection IP20 guarantees protection against accidental contact and against the ingress of solid bodies larger than 12.5 mm.
• Adapted to needs: The setting range of the overload release allows you to adapt the switch to specific loads in the installation.
• Screw connection: Provides a secure and durable connection of wires to the switch.

Technical parameters – what you should know

The Z-TS20/1 switch is a single-pole (1P) device, which means it is used to protect a single electrical circuit. It does not have an integrated auxiliary contact or undervoltage release. Power losses are 3.3 W, which affects the energy efficiency of the installation. It is also important that the device does not have phase failure sensitivity - it will not switch off the circuit in the event of a loss of one of the supply phases. The rated operating power for AC-3 is 0 kW for both 230 V and 400 V - this indicates that the switch cannot be used to switch on three-phase motors with significant power (AC-3 is a load category related to motors).
