Retrofit for Reyrolle LMT
The latest Siemens LMT SION retrofit
circuit breaker for Reyrolle panels
represents the utmost solution and
service quality.
Siemens now supports the Reyrolle
installed based on a global basis with
a comprehensive range of services
supported from the Reyrolle Works,
situated on the original site in Hebburn,
UK. This enables Siemens to offer
complete OEM capabilities backed by the
latest manufacturing as well as research
and development activities.
LMT SION retrofit – a replacement
that pays off
LMT SION retrofit has been specifically
designed for customers to seamlessly
interface with their existing Reyrolle
panels, replacing outdated oil or SF6
circuit breaker units with a modern
vacuum circuit breaker. This can be
a simple retrofit to extend life and
minimize maintenance requirements. It
can also be part of a comprehensive
upgrade to enhance the ratings of
installed equipment. The key benefits
include:
Reduced cost of ownership,
as SION vacuum devices require
minimal maintenance and boast the
very high switching durability of
vacuum. Moreover, there is no oil or
gas to handle.
Optimized life extension of existing
switchgear.
Minimal plant outage costs,
as only minimum disruption and site
works are required and no modifications
are necessary to shutters or cable boxes.
Switchgear and Field Services
Answers for energy.
As the original equipment manufacturer,
Siemens has unparalleled knowledge and
provides outstanding service.
Low cost compared to renewal,
as a total cost and time evaluation
shows considerable advantages over
replacement in many high-density
distribution applications and also in
critical industrial applications.
Fully type-tested equipment
tested on actual panel types in
accordance with IEC 62271-200.
Fast site delivery,
in most cases within three months
after receipt of order.
A full range of services
including condition assessment, partial
discharge monitoring, etc.
Upgrades
with short circuit ratings up to 31.5 kA
and normal current enhancements
being achievable up to the maximum
possible on capability of existing
equipment. Additional extension
panels and/or protection and control
upgrades are possible if required.
Applications – verified by Siemens
Services
LMT SION has been developed using all
of the Reyrolle application engineering
knowledge acquired since the first
development of LM23T in 1963. This is
why Siemens understands the particular
application requirements of each
customer installation to ensure a
seamless and reliable retrofit solution.
Moreover, all ratings and performance
documentation can be certified, such
that risks and uncertainty are avoided.
A key part of any retrofit project are
the added-value services that can be
provided. The Siemens offer comprises:
Condition assessment
i.e., the evaluation of equipment
condition utilizing condition
monitoring techniques to assess
existing condition, including full
switchboard partial discharge
monitoring.
On our purpose-built production cell in
the UK, each LMT SION unit is guaranteed
to interface with installed panels using
the same jigs and fixtures as used for the
production of the original equipment.
SION units are assembled by Siemens Reyrolle
in Hebburn, UK – a real cost and technical
advantage.

The LMT SION retrofit circuit breaker
has been type-tested at independently
accredited test laboratories in accordance
with IEC 62271-200 and other relevant
IEC and national standards.
Tests have been completed with panels
of different types so that test evidence
can be provided to cover any specific
need and the effectiveness of the total
solution is ensured.
Interfaces with panel types have been
carefully designed to minimize dielectric
stress levels resulting in an optimized
solution.
Upgrading,
as the application of retrofit circuit
breakers may allow the equipment
ratings to be enhanced by reviewing
design, condition, and possible
modifications. A typical example is
uprating from 13.1 kA to 20 kA.
Protection and control,
comprising the simultaneous upgrade
of automation, control, and protection
schemes to make use of enhanced
functionality.
Environmental services,
particularly oil and SF6 handling,
training, decontamination, and
disposal.
The SION cassette is supplied complete
from the advanced Siemens factory in
Berlin and is fully tested as a unit before
being fitted to the purpose-designed
truck.
