Timers, Meters

Licensed electricians and electrical contractors rely on precision timing and energy monitoring equipment to deliver compliant, efficient electrical installations across residential, commercial, and industrial projects. iSupply Electrical stocks a comprehensive range of electrical timers and meters designed for DIN rail mounting inside switchboards and electrical panels, providing the control and measurement capabilities essential for modern electrical systems.​

DIN rail timers automatically control electrical circuits at predetermined intervals, enabling automated switching for lighting systems, HVAC equipment, irrigation controls, industrial machinery, and energy management applications. Available in both analog countdown units and digital programmable time switches, these devices offer flexible scheduling options from 12-minute countdown cycles to full 7-day weekly programming. Bluetooth-enabled digital timer modules like the S-Click HNS810TM provide wireless programming convenience for complex commercial installations.​

Kilowatt-hour (kWh) meters deliver accurate energy consumption monitoring for single-phase and three-phase electrical systems, essential for sub-metering applications in multi-tenancy buildings, tenant billing verification, energy audits, and load monitoring projects. These DIN rail-mounted analog meters integrate seamlessly within distribution boards, providing licensed contractors with compliant measurement solutions for residential apartments, commercial fit-outs, and industrial facilities.​

All electrical timers and meters at iSupply Electrical meet Australian electrical standards and are suitable for professional installation by licensed electricians. Browse our complete range of circuit protection equipment including distribution boards, meter boxes, and switchboard components to complete your electrical installations. Competitive wholesale pricing, trade accounts, and fast delivery across NSW and all Australian states ensure your projects stay on schedule.​

Frequently Asked Questions

What types of electrical timers are available for switchboard installation?

DIN rail electrical timers include analog countdown timers (12-minute mechanical units for temporary control), digital programmable time switches (7-day weekly scheduling for automated lighting and equipment control), and Bluetooth-enabled digital modules that allow wireless programming via smartphone apps. All models mount directly onto standard 35mm DIN rails inside electrical panels and switchboards.​

What is the difference between single-phase and three-phase kWh meters?

Single-phase kWh meters measure energy consumption in standard residential and light commercial circuits (up to 30 amps), suitable for individual apartments, small retail tenancies, and sub-metering applications. Three-phase kWh meters monitor higher-capacity industrial and commercial electrical systems with balanced three-phase loads, essential for factories, large commercial buildings, and heavy machinery installations.​

Can licensed electricians install sub-metering equipment in multi-tenancy buildings?

Yes, licensed electricians can install DIN rail-mounted kWh meters as sub-metering equipment within distribution boards for individual tenancies in apartment complexes, commercial buildings, and mixed-use developments. These meters enable accurate tenant billing and energy monitoring while complying with Australian electrical installation standards when installed by qualified professionals.​

What applications require programmable timer switches in commercial installations?

Digital programmable timers control automated lighting systems, exhaust fans, water features, irrigation systems, display lighting, security lighting, HVAC equipment, and industrial process automation. Seven-day timers enable weekly scheduling patterns for commercial buildings requiring different operating hours across weekdays and weekends.​

Are these electrical timers and meters compatible with standard Australian switchboards?

All DIN rail timers and meters stock at iSupply Electrical mount on standard 35mm DIN rails commonly used in Australian electrical panels, distribution boards, and switchboard assemblies. This ensures seamless integration with existing circuit protection infrastructure and compliance with AS/NZS 3000 wiring standards for professional electrical installations.​
