المميزات والفوائد
- AC-23A motor load utilisation category allows switching of motor-circuit currents at rated current, making the 5ST3 suitable as a per-motor circuit isolator in sub-distribution panels feeding motor control circuits.
- Toggle-rotary handle with clear ON/OFF colour marking provides immediately visible isolation status from the panel front — a key requirement for Saudi MEW electrical inspection compliance.
- Optional padlock attachment in OFF allows LOTO procedures at individual circuit level, enabling multi-trade teams to apply personal locks on specific circuits without isolating the entire board.
- 1P through 4P configurations in a common module width cover every circuit requirement in Saudi distribution board designs, from single-phase lighting to three-phase motor sub-distribution.
- DIN rail 35 mm 2-module-per-pole format integrates into standard IEC 61439-3 enclosures alongside 5SY MCBs and 5SV RCCBs without special modifications.
- 6 kA short-circuit coordination with upstream MCBs and fuses ensures the 5ST3 withstands prospective fault currents at distribution board level in Saudi commercial and light industrial installations.
- Compact design and competitive pricing make the 5ST3 the default per-circuit isolator for Saudi panel builders assembling MDB and SDB boards for residential and commercial projects across the Kingdom.
التطبيقات الصناعية
- Per-circuit isolation in commercial building sub-distribution boards across Saudi commercial towers and government buildings, where individual circuit isolation points satisfy Saudi Electrical Regulations (SER) maintenance requirements.
- Motor circuit isolation in sub-distribution panels feeding pump, fan, and conveyor starters, where AC-23A rating ensures reliable switching of motor circuits during industrial maintenance.
- Residential villa consumer unit main switch in MEW-approved enclosures, providing the visible isolation point required by Saudi building inspection authorities for each villa distribution board.
- HVAC equipment sub-distribution isolation for AHUs, FCUs, and chiller auxiliaries in commercial buildings, where padlock option supports HVAC maintenance safety procedures.
- Retail shop board circuit isolation at shopping centres in Riyadh, Jeddah, and Dammam, allowing maintenance of individual tenant circuits without disturbing adjacent tenants.
- Light industrial workshop per-machine circuit isolation, satisfying the IEC 60204-1 requirement for a local isolation means adjacent to each piece of production equipment.
- Panel builder component supply for domestic and export panels in Saudi MODON industrial zones, where the 5ST3's availability, competitive pricing, and brand recognition facilitate OEM machine panel cost optimisation.
