The Tesla TESHWP Hot Water Pack combines the TESATS1DR Analogue Timer with the TESVS125-10 Modular Contactor, providing a DIN-rail ready solution for controlled operation of hot water systems and other resistive single-phase loads up to 25A. Pre-matched for compatibility, this bundle is ideal for domestic, commercial, and light industrial energy management applications.

The TESVS125-10 is a 2-pole modular contactor with one normally open (1NO) contact, DIN rail mountable, and rated for 230V AC operation. It supports resistive loads such as hot water heaters, ovens, motors, and ventilation equipment. The contactor offers silent switching and a robust 25A AC-1 rating at 230V, with a compact 1-module design.

Paired with the TESATS1DR Analogue Timer, the unit allows daily programmable switching in 15-minute intervals, with up to 100 hours of power reserve to retain settings after outages.

• TESVS125-10 Modular Contactor: 2-pole, 1NO, 25A AC-1 rated at 230V AC, DIN rail mountable, compact 17.5mm width.
• TESATS1DR Analogue Timer: Daily 24-hour program with 15-minute intervals, mechanical dial, and quartz accuracy.
• Power reserve up to 100 hours: Timer retains settings after loss of supply.
• DIN rail installation: Fast, standardised panel mounting for both components.
• Applications: Hot water systems, ventilation, lighting, motors, and other resistive loads.
