Schneider Electric TeSys Ultra Overload Relay

Overview

Schneider Electric TeSys Ultra is an overload relay built for industrial and commercial electrical installations in Oman and across the GCC. It combines rugged construction with proven motor overload protection performance, making it a dependable choice for panel builders and facility engineers on new installations and retrofits alike. The design accounts for the high ambient temperatures and dust loading typical of Gulf industrial sites, and technical support is available through Schneider Electric’s regional engineering network.

With fast quotation turnaround and technical support, Seven Star LLC supplies the Schneider Electric TeSys Ultra with manufacturer documentation and local technical support throughout Oman, Muscat, and the broader GCC. Buyers can source the Schneider Electric TeSys Ultra through Seven Star LLC with a formal quotation, the manufacturer datasheet and technical support with selection.

Operating Principle

The Schneider Electric TeSys Ultra continuously monitors current drawn by a connected motor across all three phases, comparing measured values against a configured thermal model that closely replicates the motor’s actual heating and cooling behaviour rather than relying on a simple fixed time-current curve. When sustained overcurrent conditions indicate a developing overload, the relay trips the associated contactor before winding temperatures reach damaging levels, protecting the motor investment.

In practice, this operating principle gives the TeSys Ultra consistent, repeatable performance over a long service life with minimal maintenance. Behaviour stays predictable under varying load and environmental conditions, and the unit integrates easily into new or existing Schneider Electric systems, including EcoStruxure-enabled monitoring architectures where applicable. That makes it a sound long-term choice for motor overload protection duties in facilities where unplanned downtime is costly.

Engineering Design of the Schneider Electric TeSys Ultra

Housed in a compact, DIN-rail or contactor-mountable enclosure, the Schneider Electric TeSys Ultra integrates adjustable current-setting dials or digital configuration alongside manual and automatic reset options, giving maintenance teams flexibility in how a tripped motor circuit is restored to service. Trip-class selection allows the relay to be matched precisely to the starting characteristics of the driven load.

Each unit goes through Schneider Electric’s standard quality and type-test regime, covering dimensional consistency, insulation performance and mechanical durability over the rated operating life. Installers in Sohar, Salalah and the Muscat governorate report straightforward commissioning and reliable long-term operation when the TeSys Ultra is installed to Schneider Electric guidelines. Seven Star LLC’s technical team can advise on sizing and installation practice before you order.

Key Features

The Schneider Electric TeSys Ultra delivers a combination of engineering benefits that make it a preferred choice for Schneider Electric motor overload protection specifiers across the region:

• Thermal-modeled overload protection closely matching real motor heating behaviour.
• Adjustable current settings and selectable trip classes for precise motor matching.
• Manual or automatic reset options suited to different operational requirements.
• Compact DIN-rail or direct contactor-mounting for space-efficient panel design.
• Phase-loss and phase-unbalance protection safeguarding against common supply faults.
• Clear trip indication simplifying fault diagnosis and maintenance response.
• Compatibility with the broader Schneider Electric TeSys contactor range.
• Long service life validated for continuous industrial duty cycles.

Industrial Applications

Pump, fan, and compressor motor circuits across Oman’s water treatment, oil and gas, and manufacturing facilities rely on the Schneider Electric TeSys Ultra to prevent costly motor burnout from sustained overload conditions. Panel builders across Muscat, Sohar, and Salalah specify the Schneider Electric TeSys Ultra as a standard companion to Schneider Electric TeSys contactors in motor starter assemblies.

Seven Star LLC supplies the TeSys Ultra to EPC contractors, panel builders and end users in Oman’s oil and gas, petrochemical, water desalination, district cooling and commercial real estate sectors. From commercial towers in Muscat to the Sohar and Salalah free zones, it is specified for greenfield projects and brownfield upgrades alike, backed by regional supply and support.
